Definitions
- the present specification relates generally to dryers for hay bales, and, in particular, to an air-injection drying system for one or more hay bales.
- hay is stored in bales, which need to be below a specific moisture level (generally 12%) to prevent spoilage during storage. This is typically done by cutting the hay, then leaving it in the fields to dry prior to being baled. Under ideal conditions, cut hay starts at approximately 75% moisture, which is reduced to around 40% within the first 24 hours and to around 25% in the next 48. However, to get down to 12% typically requires another 72 hours. Therefore, a clear weather window for 5 days is required for harvesting hay. This creates a risk of the hay being exposed to further moisture prior to baling as a consequence of a change in weather patterns. Furthermore, hay left too long may become too dry, leading to a loss of leaves and a reducing harvest.
- a specific moisture level generally 126%
- an air injection hay bale dryer using spikes to penetrate the interior of the hay bale.
- a hay bale dryer comprising: a platform, the platform dimensioned to support the hay bale; a spike rack movably coupled to the platform, the spike rack having a plurality of spikes, each spike having a plurality of slots and each spike dimensioned to penetrate through the hay bale; a fan coupled to the spike rack and operative to blow air through the slots in the spikes, wherein the spike rack is raised to permit loading and unloading of the hay bale, and lowered to permit drying of the hay bale via the air blown through the spikes.
- a hay bale drying system comprising: a plurality of hay bale dryers, each hay bale dryer comprising: a platform, the platform dimensioned to support the hay bale; and a spike rack movably coupled to the platform, the spike rack having a plurality of spikes, each spike having a plurality of slots and each spike dimensioned to penetrate through the hay bale.
- the hay bale drying system further comprises a fan coupled to each of the hay bale dryers in line and operative to blow air through the slots in the spikes, wherein each spike rack is independently raised to permit loading and unloading of its respective hay bale, and lowered to permit drying of the hay bale via the air blown through the spikes.
- a method of drying a hay bale located on a platform to a desired moisture level comprising: lowering a spike rack movably coupled to the platform, the spike rack having a plurality of spikes, each spike having a plurality of slots and each spike dimensioned to penetrate through the hay bale; activating a fan coupled to the spike rack to blow air through the spikes; and raising the spike rack once the process is complete.
- the present invention is a dryer for hay bales and, in particular, to an air injection dryer for hay bales.
- the dryer 100 consists of a platform 110 and a spike rack 120.
- Spike rack 120 may be raised to permit insertion of a hay bale (not shown) as in Figure 1A , and may be lowered to perform the drying process, as in Figure 1B .
- Each spike 130 in spike rack 120 is coupled via piping 140 to permit air to flow through the piping 140 into spike rack 120 and into each spike 130.
- Spike rack 120 may be raised and lowered by a hydraulic mechanism, and a spike guide 125 may be attached to the platform 110 to guide the spikes 130 into the hay bale. When lowered, the tips of spikes 130 should not contact the base of platform 110.
- each spike 130 may be formed from a body 132, with a number of slots 134.

Description
- The present specification relates generally to dryers for hay bales, and, in particular, to an air-injection drying system for one or more hay bales.
- After harvesting, hay is stored in bales, which need to be below a specific moisture level (generally 12%) to prevent spoilage during storage. This is typically done by cutting the hay, then leaving it in the fields to dry prior to being baled. Under ideal conditions, cut hay starts at approximately 75% moisture, which is reduced to around 40% within the first 24 hours and to around 25% in the next 48. However, to get down to 12% typically requires another 72 hours. Therefore, a clear weather window for 5 days is required for harvesting hay. This creates a risk of the hay being exposed to further moisture prior to baling as a consequence of a change in weather patterns. Furthermore, hay left too long may become too dry, leading to a loss of leaves and a reducing harvest.
- It would be preferable to harvest hay at a 25% moisture level, and then to dry the bales to the required moisture level thereafter. This would reduce the required weather window significantly, as well as enabling earlier field irrigation to reduce the chances of plants going dormant. However, drying hay bales presents a challenge. Hay bales are generally quite large in size (typically 3 feet by 4 feet by 8 feet) and drying the interior hay flakes through exterior drying means is difficult. Ideally, a drying process should penetrate the interior of the hay bale, as well as enabling reasonably rapid drying of high-moisture bales.
- Accordingly, there remains a need for improvements in the art.
- In accordance with an aspect of the invention, there is provided an air injection hay bale dryer using spikes to penetrate the interior of the hay bale.
- According to an embodiment of the invention, there is provided a hay bale dryer, comprising: a platform, the platform dimensioned to support the hay bale; a spike rack movably coupled to the platform, the spike rack having a plurality of spikes, each spike having a plurality of slots and each spike dimensioned to penetrate through the hay bale; a fan coupled to the spike rack and operative to blow air through the slots in the spikes, wherein the spike rack is raised to permit loading and unloading of the hay bale, and lowered to permit drying of the hay bale via the air blown through the spikes.
- According to another embodiment of the invention, there is provided a hay bale drying system, comprising: a plurality of hay bale dryers, each hay bale dryer comprising: a platform, the platform dimensioned to support the hay bale; and a spike rack movably coupled to the platform, the spike rack having a plurality of spikes, each spike having a plurality of slots and each spike dimensioned to penetrate through the hay bale. The hay bale drying system further comprises a fan coupled to each of the hay bale dryers in line and operative to blow air through the slots in the spikes, wherein each spike rack is independently raised to permit loading and unloading of its respective hay bale, and lowered to permit drying of the hay bale via the air blown through the spikes.
- According to another embodiment of the invention, there is provided a method of drying a hay bale located on a platform to a desired moisture level, comprising: lowering a spike rack movably coupled to the platform, the spike rack having a plurality of spikes, each spike having a plurality of slots and each spike dimensioned to penetrate through the hay bale; activating a fan coupled to the spike rack to blow air through the spikes; and raising the spike rack once the process is complete.
- Other aspects and features according to the present application will become apparent to those ordinarily skilled in the art upon review of the following description of embodiments of the invention in conjunction with the accompanying figures.

- The present invention is a dryer for hay bales and, in particular, to an air injection dryer for hay bales.
- According to an embodiment as shown in
Figures 1A and1B , thedryer 100 consists of aplatform 110 and aspike rack 120.Spike rack 120 may be raised to permit insertion of a hay bale (not shown) as inFigure 1A , and may be lowered to perform the drying process, as inFigure 1B . Eachspike 130 inspike rack 120 is coupled viapiping 140 to permit air to flow through thepiping 140 intospike rack 120 and into eachspike 130.Spike rack 120 may be raised and lowered by a hydraulic mechanism, and aspike guide 125 may be attached to theplatform 110 to guide thespikes 130 into the hay bale. When lowered, the tips ofspikes 130 should not contact the base ofplatform 110. - As shown in
Figure 3 , eachspike 130 may be formed from abody 132, with a number ofslots 134. The number, spacing and size of theslots 134 is determined by the size of the bale, the estimated average size of the hay flakes within the bale (typically 5 to 6 inches) and the fan pressure and corresponding desired air flow output through the spike. As an example, for a 3x4x8 hay bale,spikes 130 are arranged in 5 staggered rows, in three rows of 16 and 2 rows of 15 (see pattern inFigure 5 ), for 78spikes 130, with 6 slots perspike 130. For other bale sizes, different configurations may be used. For example, a 3x3x8 may have only four rows of spikes, whereas a 4x4x8 bale may require longer spikes and more slots. The desired air flow of per bale, or perspike 130 will depend on the fan pressure and the size of theslots 134. As shown inFigure 3 ,spike 130 may have adetachable tip 136 and adetachable connector 138 to spikerack 120, to simplify cleaning, however,spike 130 may alternatively be formed as a single unitary piece secured to spikerack 120. - Referring to
Figure 4 , a plan view of theplatform 110 is provided.Platform 110 includes abale trap 165 to support the hay bale with afront apron 170 for loading the bale. Abale guide 175 may be provided to align the bale on theplatform 110 with thespike rack 120, as shown inFigure 5 . -
Figure 5 provides a plan view ofplatform 110 andspike guide 125. As discussed above for a 3x4x8 bale, 78spikes 130 are arranged in 5 staggered rows (3x16 and 2x15) disposed within the area defined by thefront apron 170 andbale guide 175.Figure 6 shows the full assembly ofspike rack 120 overlaying theplatform 110. -
Figure 7 shows a plan view ofpiping 140 overlayingspike rack 120 andplatform 110.Piping 140 should be flexible, to permit the raising and lowering ofspike rack 120 without compromising the integrity ofpiping 140. As shown,piping 140 has a Y-split to drive down two sides ofspike rack 120, however, a single piping channel may be used, depending on the required airflow, number of spikes, and fan air pressure. - In operation, a hay bale is loaded onto
platform 110 withspike rack 120 raised.Front apron 170 allows the hay bale to be manually pushed onto thebale trap 165, withbale guide 175 acting to keep the bale aligned to theplatform 110 and spikerack 120. - Once the hay bale is loaded,
spike rack 120 is lowered, withspike 130 passing throughspike guide 125 and into the hay bale. As shown above, spikes 130 pass substantially through the hay bale, but do not contact theplatform 110. With thespikes 130 in place, the drying process may begin. - To dry the bale, a fan 180 (as shown in
Figure 8 ) is activated to force air through thepiping 140 and into thespike rack 120 and out theslots 134 in thespikes 130 to dry the hay flakes within the hay bale. When the prescribed drying time for the drying process is completed,spike rack 120 may then be raised to remove the spikes and the dry hale bale pushed through the platform..A new bale may then be placed on the platform as described and the process repeated until all bales are dry. - Using a
pressure blower fan 180 to dry 3x4x8 hay bales using the five-row spike pattern described above, it was found a hay bale could be dried from approximately 25%+ moisture to 12% moisture in 10 to 15 minutes. Thus, hay may be baled at 25%+ moisture and dried to 12% moisture viahay bale dryer 100, reducing the harvesting time by 1-3 days, depending on climate conditions. - It has been found that with an electric- or diesel-powered fan, it may be possible that the heat of operation of the
fan 180 is sufficient to heat the air and remove moisture as a result, permitting the drying of hay bales without additional equipment. However, in particularly cool or humid climates, or when operating at night, it may be desirable to include a heater and/or a dehumidifier as part of thefan 180. Caution should be taken to avoid overheating the air as excessive heat may lead to spoilage of the hay bale. - Referring to
Figure 8 , to increase efficiencies and throughput, a plurality ofhay bale dryers 100 may be connected together in line to a single fan 180 (and, optionally, heater and dehumidifier). The total number ofdryers 100 operable is determined by the power offan 180. As shown, thedryers 100 are grouped in line. The piping 140 for eachdryer 100 is then connected in parallel along the main line. In testing, it was found the six or more dryers may be connected per channel without a loss in performance, for a total of six or more dryers operating from asingle fan 180 as an air source. - Alternatively, the plurality of
hay bale dryers 100 may be connected to thefan 180 in using one or more Y-split pipes. The overall layout offan 180 anddryers 100 may be determined by the volume of hay bale to be dried, the space available for loading bales and locating thedryers 100 and, as discussed above, the required airflow through thespikes 130 and power offan 180. - The present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. Certain adaptations and modifications of the invention will be obvious to those skilled in the art. Therefore, the presently discussed embodiments are considered to be illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than the foregoing description and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
